The nucleophilic substitution of diarylmethyl carbonates with malonate carbanions proceeded in the presence of [Pd(π-C<SUB>3</SUB>H<SUB>5</SUB>)(cod)]BF<SUB>4</SUB>–Cy-Xantphos, giving the desired (diarylmethyl)malonates in up to 90% yield. The yield was extremely affected by choice of the phosphine ligand.
